I do find questions like "What's the point of existence?" or "What's the reason for existence?" rather... uh... pointless. (pun intended)
This is related to my doubts about causality.
At any rate, I tend to be more interested in what is, as well as how to respond to what is. As plain as I can put it, beyond that language doesn't work (the failure of language being related to the failure of questions like "What's the point?" and "What's the reason?").
